Be it ki'iovrn that l, liban lanuarn, s, citi z'en of the 'United States, i siding at Kiran` ball, in tbe county of Kimball and State oi Nebraslm, have invented a new and useful Subsurface liandrlacker, ci which tbe toim lowing is a specification.

The invention relates `'to a subsurface land packer. o

The object of the present invention is to improve the construction oit land packers, and to provide a simple, ecient andconiw paratiyely inexpensive land packer, equipped Mention.

Like numerals of reference designate corresponding ,parte in all the gurcs of the drawings.

In the accompanying drawings in which is illustrated the nreerr'ed embodiment oi" the invention, the and'packer preferably comprises in its construction two separate sections or series of packing Wheels l, the series or gangs of Wheels being capable of a limited independent vertical movement yto adjust themselves to suit the character of the land. The sections of packing Wheels are adapted to roll closer to the; ground and pack tbe .latter more evenly than a single continu 5,5

ous series. Loose plowed ground may be packed and by using a spiked tooth barrow on it once a sibile, the suriace may be kept soit and loose. ribis will cause the ed in alined transverse axles 2, journaled 'in suitable bearings 3 volf' brackets d. The brackets consist ci approximately U- sbaped upper portions and lower stems, and tbe. l'iearings, Wbicb are arranged at the lowerl ends of tbe stems, aref preferably equipped with bushings 5 of Wood, or other .suitable material secured in the bearings by set screws 6, or other suitable fastening means. The stems ol? tbe brackets are provided, vertical oil passages 4.-, extendiirom tbe space betweentbe arms of the brackets downwardly tlirougb the stems and communicating with openings-5 in the bones or bushings 5. The oil passages, which7 are adapted' 'to contain a lubricant of bard' oil or grease, are threaded for the reception of screws 4C, adapted to form cloeures tor the oil passages and for forcing the lubricant into the boxes. The brackets are located opposite ends ot the transverse azules, and tbe arms ci the several bearing brackets are transversely alined and are provided at their upper ends with recesses 7, formi; seats for horizontally disposed oblong trainee 8. The oblong' frames 8,-Whicl1 are located at opposite sides et the center of tbe machine, are preferably constructed. of angle iron or other suitable anged matcrial, and are composed of Vfront and rear sides and connecting ends, and 'they are secured to Atbedront andv rear sides of tbe frame by bolts 9,-or other suitable fastening devices.

The `packing Wheels, which are relatively heavy, are provided withl oppositely beveled .rims .10, connected Vby spokes ll With hubs 12, which are arranged on the axles 2. .The sections of the machine may consist of any suitable number of packing Wheels, and the u land packer may be varied in size by removing the Wheels from the ends of thesctions. To facilitate this operation,` the axles are preferably provided at their outer ends with nuts 2, and two of the packing Wheels of eacb series are located beyond the outer bearing brackets, which may be arranged at any desired points. .The oppositcly beveled liti them to crush clods, pulverize the soil at i the surface and pack the sub-soil.

The lower portions or stems of the brackets 4 are pivoted in forks or bifurcations 14 of inner and outer links 15 and 16 by pins 13, which pierce the stems in advance of the oil passages 4a. The outer links 16 are provid rd at theirfront ends with eyes 17, through which pass the terminals 18 of a transversepivot bar 19,-centrally secured to the lower face of the rear end of a tongue 20 by means o'f aclip plate 21. The clip plate 21, which is provided at its center with a Ybowed or bent portion 22 to receive the pivot bar, is fastened to the tongue by means of vertical bolts 23, which also pierce the lower end of a standard 24 of a seat 25 for the acc tion of the driver.

The transverse pivot bar is arrangedin advance of and in parallelism with the two Series of packing wheels, and the inner longitudinal links 15, which are of greater length than the outer' links, extend beneath the transverse pivot bar and have their front portions 26 curved upward and arranged at opposite sides of and pivoted to the side faces of the tongue in advance of the transverse pivot bar by means ofV a transverse bolt 27, or other suitable fastening device. The series of wheelsare adapted to swing upwardly and downwardly on the pivots of the front ends of the links 15 and 16, and the inner links 15 are arranged to swing against the transverse pivot mmodabar to limit the relative upward movement of the packing wheels, so that t-he same will be held in the ground by the weight of the driver in addition to their own weight and the weight of the oblong frames, `which form convenient means for mounting weighted boxes or receptacles upon the inachine. The frames are maintained in an upright' position by inclined braces 28, bolted or otherwise secured at their rear upper ends to the front side bars of the. frames at the centers thereof, and provided at their lower front ends with openings 29, through which the transverse pivot bar passes. The openings 29 are elongated to permit the necessary play of the parts incident to the up and 'down or vertical movement of the frames through the pivoted longitudinal links, and the said braces do not interfere with such up and down movement.` The inner and outer longitudinal links owing to their difference in length have a different arc of movement, and while they do not permit an unlimited movement of the packing wheels, such movement is sufficient, but the up and down movement of thc series of packing wheels is sufficient to enable them to adjust themselves to the character of the land operated on.

spring' The outer portions of the transverse pivot bar are connected with the tongue by rearwardly diverging side braces 30, provided at their rear ends witheyes 31 toreceive the pivot bar and having their front terminals 32, bent at an angle and secured to the side .faces of the tongue by transverse bolts 33.

tongue with the end portions of a double# tree'35 by stay chains 36, or other flexible connections. The stay chains 36 are secured at their rear ends to the transverse pivot bar by clamping collars 37, arranged on the pivot bar and having forwardly extending terminals, pierced by vertical bolts 38, which alsor pass through the end links of the chains 36. The chains 36 are equipped at their front ends with hooks 39, which detachably engage eye bolts 40. The eye bolts 40, which are horizontal, pierce the end portions of the doubletree, Abeing provided at their rear ends with eyes and at theii1 front ends with nuts. The doubletree is pivoted to the tongue preferably at the upper face 1.
